CPAP and Physiotherapy for Heart Failure and Sleep Apnea in the Elderly

July 2, 2025 updated by: Weihua Peng

The Impact of Continuous Positive Airway Pressure Combined With Physiotherapy on Ejection Fraction by Ameliorating Sleep Disturbance and Hypoxemia in Elderly Patients With Chronic Heart Failure and Obstructive Sleep Apnea: A Randomized Clinical Trial

This study evaluates whether adding physiotherapy (including herbal medicine, acupuncture, and Tuina massage) to standard continuous positive airway pressure (CPAP) therapy can provide superior benefits compared to CPAP alone for elderly patients suffering from both chronic heart failure (CHF) and obstructive sleep apnea (OSA). This randomized controlled trial aims to determine the combined therapy's efficacy and safety in improving sleep quality, hypoxemia, and cardiac function.

Study Overview

Detailed Description

The coexistence of chronic heart failure (CHF) and obstructive sleep apnea (OSA) in elderly patients creates a vicious cycle, worsening prognosis. Continuous positive airway pressure (CPAP) is the first-line treatment for OSA, but its efficacy in improving cardiac function in patients with comorbid CHF is debated. This prospective, randomized controlled trial was designed to evaluate the clinical efficacy of a comprehensive intervention combining CPAP with physiotherapy (herbal medicine, acupuncture, and Tuina massage). The study hypothesizes that this combined approach will be more effective than CPAP alone in improving sleep disturbances (assessed by the Pittsburgh Sleep Quality Index and Apnea-Hypopnea Index), alleviating hypoxemia (assessed by arterial blood gas analysis), and favorably modulating left ventricular ejection fraction (EF), thereby offering a superior management strategy for this complex patient population.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Study Group: CPAP plus Physiotherapy
In addition to receiving the same CPAP therapy as the control group, patients in this arm received a 3-month physiotherapy regimen. The regimen consisted of: 1) Daily oral administration of a modified herbal decoction (Er Chen Tang with Chang Pu Yu Jin Tang); 2) Acupuncture sessions, once daily, 5 times per week; and 3) Head and occipital Tuina massage.
Using a ResMed S9 AutoSet-S device with a pressure range of 4-20 cmH2O. Used for 5-7 hours per night, at least 5 nights per week, for 3 months.
A daily dose of a decoction containing Ban Xia, Ju Hong, Shi Chang Pu, Yu Jin, Lai Fu Zi, Fu Ling, Bai Zhi, Cang Er Zi, and Gan Cao, administered orally in two divided doses.
Daily sessions with needle retention for 30 minutes, 5 times per week. Acupoints included Anmian (EX-HN22), Lianquan (CV23), Shanzhong (CV17), Zhongwan (CV12), Kongzui (LU6), Pishu (BL20), Fenglong (ST40), Zusanli (ST36), Yinlingquan (SP9), and Zhaohai (KI6).
Includes massage techniques applied to the head and occipital region to relax muscles and improve local circulation.
Active Comparator: Control Group: CPAP Alone
Patients received CPAP therapy using a ResMed S9 AutoSet-S device. An optimal pressure or auto-adjusting range was determined via pressure titration. Patients were instructed to use the device for 5-7 hours per night, at least 5 nights per week, for 3 months. All patients also received standard conventional management for CHF and lifestyle advice.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Left Ventricular Ejection Fraction (EF)
Time Frame: Baseline and 3 months post-treatment
Measured by echocardiography to compare the change in EF from baseline to 3 months post-treatment. EF (%) = (EDV - ESV) / EDV × 100%.
Baseline and 3 months post-treatment
Change in Pittsburgh Sleep Quality Index (PSQI) Score
Time Frame: Baseline and 3 months post-treatment
To assess sleep quality. The total score ranges from 0-21, with higher scores indicating poorer sleep quality.
Baseline and 3 months post-treatment
Change in Apnea-Hypopnea Index (AHI)
Time Frame: Baseline and 3 months post-treatment
Measured by overnight polysomnography, defined as the total number of apneas and hypopneas per hour of sleep.
Baseline and 3 months post-treatment
Change in Arterial Oxygen Saturation (SaO2)
Time Frame: Baseline and 3 months post-treatment
Measured via arterial blood gas analysis to assess improvement in hypoxemia.
Baseline and 3 months post-treatment
